Description

一种冲洗马桶盖 技术领域
本发明涉及马桶盖制造技术领域，尤其是一种冲洗马桶盖。
背景技术
现有的冲洗马桶盖在冲洗过程中，为了尽量不提高产品的加热功率及保证水温响应，清洗流量一般需控制在400-1200ml/Min范围内，由于有这个流量稳定性的要求，冲洗马桶盖需要安装减压稳流阀组件来保证产品在不同工作水压下的流量稳定性。为了防止供水前端的高压传递到产品的出水管路中，致使软管及软管接头脱出产生泄露，因此市面上的冲洗马桶盖都要在减压稳流阀组件的前端加上一个常闭的电磁阀组件，在产品未工作时，电磁阀关闭，起截断产品与供水管道高压保护软管及软管接头的功能，当接收到清洗信号后，电磁阀开启工作。但是这种设置就会使冲洗马桶盖结构和控制复杂化，提高冲洗马桶盖的制造成本，也不利于冲洗马桶盖的结构布置，且在断电的情况下无法进行冲洗。
发明内容
本发明要解决的技术问题是提供一种冲洗马桶盖，其结构和控制较为简化，有利于降低制造成本，且断电时也可进行冲洗。
为达到上述目的，本发明的技术方案是：一种冲洗马桶盖，包括座圈、盖板和壳体，座圈和盖板的后部铰接在壳体上，壳体内装有减压稳流阀、加热组件、开关阀、冲洗组件和控制板，减压稳流阀设有进水通道和出水通道，开关阀设有一个进水口和至少一个出水口，冲洗组件包括至少一根冲洗管，冲洗管上装有可伸缩的冲洗喷头，冲洗管上设有进水口；
减压稳流阀的进水通道连通外部进水管，减压稳流阀的出水通道通过管道连通加热组件的进水口，加热组件出水口连通开关阀的进水口，开关阀的出水口通过管道连通所述冲洗管的进水口；
所述控制板控制加热组件的工作状态，所述开关阀处于关闭状态时所述减压稳流阀截断其进水通道和出水通道。
优选所述开关阀设有两个出水口，冲洗组件包括两根冲洗管，每根冲洗管上装有一根可伸缩的冲洗喷头，每根冲洗管上设有一个进水口；开关阀上的两个出水口分别通过两根管道连通两根所述冲洗管上的进水口，开关阀上装有一个旋钮，旋转旋钮可使开关阀处于关闭状态或使开关阀的进水口与其上的一个出水口连通。通过旋转旋钮可以方便冲洗操作。
进一步改进，所述壳体内还装有一个电磁换向阀和一根自洁管，电磁换向阀设有第一端口、第二端口和第三端口，自洁管设有一个进水口和至少一个出水口，所述加热组件出水口先通过管道连通电磁换向阀的第一端口，所述开关阀的进水口再通过管道连通电磁换向阀的第二端口，电磁换向阀的第三端口通过管道连通自洁管的进水口，自洁管设置在所述冲洗喷头上面，所述冲洗喷头未工作时，自洁管的出水口对准冲洗喷头的喷水口；电磁换向阀通电时，所述第一端口和第三端口相连通，电磁换向阀断电时，所述第一端口和第二端口相连通；控制板判断所述加热组件有水流通过时先按设定时间接通电磁换向阀电源然后再切断电磁换向阀电源。这样使得本发明不仅能对冲洗喷头进行自动清洁，确保冲洗动作的可靠性，还能提高冲洗的安全性和舒适性
优选所述加热组件包括一个内腔和设置在内腔里的电加热管，加热组件的进水口处设置一个流量传感器，流量传感器电连接控制板，所述开关阀打开时，流量传感器检测到有流量并把这个信号传输给控制板，控制板接通加热组件中的电加热管电源开始加热。
优选所述减压稳流阀包括阀体、阀芯，所述进水通道和出水通道设置在阀体上，阀体内腔通过一隔层分为高压腔和低压腔，高压腔连通进水通道，低压腔连通出水通道，隔层上设有第一连通孔，第一连通孔连通高压腔和低压腔；阀芯穿过第一连通孔一端处于低压腔、另一端处于高压腔；低压腔一侧的阀体上装有一膜片，阀芯一端固连膜片，膜片远离高压腔一侧连接一压簧；高压腔一侧的阀体上设有一凹腔，阀芯另一端插入所述凹腔，阀芯另一端外侧面与所述凹腔内侧面之间设有密封圈；阀芯上设有第二连通孔，第二连通孔连通所述低压腔和所述凹腔底部；隔层处于高压腔一侧且在第一连通孔的周边固连一密封垫，阀芯处于高压腔的部分设有一肩台，当低压腔的压力升高至设定值时，低压腔的水压驱动膜片且经第二连通孔传递至所述凹腔然后克服所述压簧的弹力推动阀芯向低压腔一侧移动至所述肩台端面压住所述密封垫时，所述第一连通孔被封闭。采用这种减压稳流阀结构紧凑、动作可靠，确保在其出水通道停止出水时即所述开关阀关闭时，切断高压腔和低压腔，隔断供水前端的高压，保护减压稳流阀后端的软管和软管接头。
进一步改进，所述隔层处于高压腔一侧且在第一连通孔的周边向外延伸有第一环形凸起，所述密封垫环绕所述第一环形凸起，所述密封垫的厚度小于所述第一环形凸起的高度，所述肩台与所述密封垫相配合的端面上设有环形凹槽，所述第一环形凸起可伸入所述环形凹槽，第一环形凸起伸入所述环形凹槽时，所述环形凹槽内周面与所述第一环形凸起的外周面之间留有间隙。这样既防止密封垫被高压水挤压变形或者冲出，又能较好调节高压腔的水进入低压腔的过流截面，起到更好减压和稳流的作用。
再进一步，所述环形凹槽内周面靠近所述第一环形凸起的一端设有第一倒角，所述第一环形凸起内周面靠近所述环形凹槽一端设有第二倒角；第一倒角可起导正作用，第二倒角方便水流过第一连通孔；
所述阀体内侧面与所述隔层处于高压腔一侧的连接处间隔设有多个凸筋，凸筋的高度小于所述第一环形凸起的高度。通过多个凸筋可以防止密封垫安装不到位。
优选所述第二连通孔包括设在阀芯处于低压腔部分的第一径向通孔和设在阀芯处于高压腔端部一个U形槽及连通第一径向通孔和U形槽的阀芯上的一个轴向孔。
优选所述阀体包括阀本体、第一盖体和第二盖体，所述进水通道和出水通道设在阀本体上，所述隔层设在阀本体内腔中部，第一盖体固连阀本体一端，第二盖体固连阀本体另一端，第一盖体与所述隔层一侧及阀本体内壁构成所述低压腔，第二盖体与所述隔层另一侧及阀本体内壁构成所述高压腔，所述膜片夹在第一盖体与阀本体一端之间，所述压簧处于第一盖体与膜片之间。采用这种结构的阀体，方便制造和装配。
再进一步，所述膜片中部两侧均垫有金属垫片，阀芯一端穿过两个金属垫片及膜片并旋有一个锁紧螺母，旋紧锁紧螺母把阀芯一端和两个金属垫片及膜片固连在一起，所述第一盖体外端面中间设有一通孔，通孔上旋接一个调整螺母，所述压簧一端抵在一个金属垫片上、另一端抵在调整螺母上；通过旋转调整螺母可调整压簧的弹力，以便于调整整个减压稳流阀的工作参数；
所述金属垫片的边缘向外延伸有凸缘，所述隔层处于低压腔一侧设有多个凸块，处于低压腔的金属垫片的凸缘与所述凸块相接触时限制压簧继续驱动膜片向高压腔一侧移动，相邻凸块之间的空间形成过水通道；这样可以较好保护膜片，防止膜片的过渡变形。还能确保水能从出水通道流出；
所述第二盖体向靠近所述隔层一侧延伸有第二环形凸起，第二环形凸起的端面压住所述密封垫；第二环形凸起中间形成外大内小阶梯形凹孔，阶梯形凹孔的小孔部分形成所述凹腔，第二环形凸起上设有多个连通阶梯形凹孔大孔部分的第二径向孔，至少有一个第二径向孔对应所述进水通道。这样可防止高压水绕到密封垫背部挤出密封垫。
本发明由于开关阀处于关闭状态时所述减压稳流阀截断其进水通道和出水通道。这样就可隔离供水前端的高压，无需在减压稳流阀组件的前端再加上一个常闭的电磁阀组件，简化冲洗马桶盖的结构和控制，方便冲洗马桶盖的结构布置，可有效降低制造成本，且操作也较为简单。另一方面，由于无需设置常闭电磁阀，因此本发明在且断电时也可进行冲洗，有效提高了冲洗马桶盖的设备使用率。

具体实施方式
下面结合附图和具体的实施方式对本发明作进一步详细说明。
图1至图19所示，一种冲洗马桶盖，包括座圈10、盖板20和壳体30，座圈10和盖板20的后部铰接在壳体30上，所述壳体30包括安装底板301和罩壳302，座圈10和盖板20的后部具体与壳体30上的罩壳302相铰接，罩壳302与安装底板301通过螺丝相固紧或通过卡接方式相卡紧；安装时，安装底板301固连在陶瓷马桶上。
壳体30的安装底板301上装有减压稳流阀40、加热组件50、电磁换向阀60、开关阀70、冲洗组件80、自洁管90和控制板100，减压稳流阀40设有进水通道14和出水通道15，电磁换向阀60设有第一端口601、第二端口602和第三端口603，开关阀70设有一个进水口和两个出水口，自洁管90设有一个进水口901和两个出水口902，冲洗组件80包括 两根冲洗管801，每根冲洗管801上装有一根可伸缩的冲洗喷头802，每根冲洗管801上设有一个进水口；
减压稳流阀40的进水通道14连通外部进水管，减压稳流阀40的出水通道15通过管道连通加热组件50的进水口，加热组件50出水口通过管道连通电磁换向阀60的第一端口601，开关阀70的进水口通过管道连通电磁换向阀60的第二端口602，电磁换向阀60的第三端口603通过管道连通自洁管90的进水口901，开关阀70的两个出水口分别通过管道连通两根所述冲洗管801的进水口；
所述自洁管90设置在所述冲洗喷头802上面，所述冲洗喷头802未工作时，自洁管90上的两个出水口902分别对准两根冲洗喷头802上的喷水口；所述电磁换向阀60通电时，所述第一端口601和第三端口603相连通，电磁换向阀60断电时，所述第一端口601和第二端口602相连通；控制板100判断加热组件50有水流通过时控制加热组件50加热输出热水；控制板100判断所述加热组件50有水流通过的同时先按设定时间(时间可设定为5-8秒)接通电磁换向阀60电源然后再切断电磁换向阀60电源。
所述开关阀70为机械控制的换向阀，开关阀70的阀芯上固连一个旋钮701，旋转旋钮701可使阀芯处于三个位置，开关阀70有三种工作状态，也就是旋转旋钮701使阀芯处于第一位置并使开关阀70处于关闭状态时，冲洗组件80的两根冲洗喷头802均不工作；旋转旋钮701使阀芯处于第二位置并使开关阀70的进水口与其中一个出水口连通时，即开关阀70处于第一种打开状态时，水压可驱动冲洗组件80的一根冲洗喷头802伸出至座圈10的中间进行冲洗，如可用于臀洗；旋转旋钮701使阀芯处于第三位置并使开关阀70的进水口与另外一个出水口连通时，即开关阀70处于第二种打开状态时，水压可驱动冲洗组件80的另一根冲洗喷头802伸出至座圈10的中间进行冲洗，如可用于妇洗。
所述加热组件50可采用即热组件，所述加热组件50包括一个内腔和设置在内腔里的电加热管，加热组件50在其进水口处设置一个流量传感器，流量传感器电连接控制板100，一旦开关阀70打开，流量传感器就会检测到有流量并把这个信号传输给控制板100，控制板100就能接通加热组件50中的电加热管电源开始加热，同时控制板100还能接通电磁换向阀60电源数秒(如5-8秒，时间可以预先设定)后再切断电磁换向阀60电源。使得刚接通的水进入自洁管90对冲洗喷头802的喷水口进行清洗，以防止刚出水的水温较冷给人带来的不适，或频繁出水防止刚出水的水温较高烫伤人。
图16至图18进一步所述，所述电磁换向阀60还包括有阀体604、电磁线圈605、铁芯606、塞头607和弹簧608，电磁换向阀60的第一端口601、第二端口602和第三端口 603设置在阀体604上，铁芯606和弹簧608装在电磁线圈605的中心孔中，铁芯606一端固连塞头607、另一端连接弹簧608。当电磁线圈605未通电时，如图17所示，弹簧608推动铁芯606前移，铁芯606带动塞头607堵住第三端口603的通道，此时第一端口601和第二端口602相连通；当电磁线圈605通电时，如图18所示，电磁线圈605产生的吸力克服弹簧608的弹力使得铁芯606后缩，铁芯606带动塞头607堵住第二端口602的通道，此时第一端口601和第三端口603相连通。
图4至图15进一步所示，所述减压稳流阀40包括阀体1、阀芯2，阀体1包括阀本体11、第一盖体12和第二盖体13，进水通道14和出水通道15设置在阀本体11，阀本体11内腔中部设有一隔层16，第一盖体12用螺栓固连阀本体11一端，第二盖体13用螺栓固连阀本体11另一端，第一盖体12与所述隔层16一侧及阀本体11内壁构成阀体1的低压腔17，第二盖体13与所述隔层16另一侧及阀本体11内壁构成阀体1的高压腔18，即阀体1内腔通过一隔层16分为高压腔18和低压腔17，高压腔18连通进水通道14，低压腔17连通出水通道15，隔层16上设有第一连通孔161，第一连通孔161连通高压腔18和低压腔17。
阀芯2穿过第一连通孔161一端处于低压腔17、另一端处于高压腔18；低压腔17一侧的阀本体11上装有一膜片3，膜片3的边缘夹在第一盖体12与阀本体11一端之间；阀芯2一端固连膜片3，膜片3远离高压腔18一侧连接一压簧4，具体结构为：所述膜片3中部两侧均垫有金属垫片31，阀芯2一端穿过两个金属垫片31及膜片3并旋有一个锁紧螺母32，旋紧锁紧螺母32把阀芯2一端和两个金属垫片31及膜片3固连在一起，所述第一盖体12外端面中间设有一通孔121，通孔121上旋接一个调整螺母122，所述压簧4一端抵在一个金属垫片31上、另一端抵在调整螺母122上。通过调整螺母122可以方便调整压簧4的弹力，以方便调整减压稳流阀40的工作参数。
高压腔18一侧的阀体1上设有一凹腔19，具体结构为，所述第二盖体13向靠近所述隔层16一侧延伸有第二环形凸起131，第二环形凸起131中间形成外大内小阶梯形凹孔132，阶梯形凹孔132的小孔部分形成所述凹腔19，阀芯2另一端插入所述凹腔19，阀芯2另一端外侧面与所述凹腔19内侧面之间设有密封圈191；阀芯2上设有第二连通孔21，第二连通孔21连通所述低压腔17和所述凹腔19底部；第二连通孔21包括设在阀芯2处于低压腔17部分的第一径向通孔211和设在阀芯2处于高压腔18端部一个U形槽212及连通第一径向通孔211和U形槽212的阀芯2上的一个轴向孔213。
隔层16处于高压腔18一侧且在第一连通孔161的周边固连一密封垫5，具体结构 为，密封垫5为圆环形橡胶垫或硅胶垫，所述隔层16处于高压腔18一侧且在第一连通孔161的周边向外延伸有第一环形凸起162，所述密封垫5环绕所述第一环形凸起162，所述密封垫5的厚度小于所述第一环形凸起162的高度；第二盖体13上的第二环形凸起131的端面压住所述密封垫5，使得密封垫5与隔层16处于高压腔18一侧形成固连；所述第二环形凸起131上设有四个连通阶梯形凹孔132大孔部分的第二径向孔133，其中一个第二径向孔133对应所述进水通道14。第二径向孔133起到过流的作用。
阀芯2处于高压腔18的部分设有一肩台22，当低压腔17的压力升高，低压腔17的水压驱动膜片3且经第二连通孔21传递至所述凹腔19然后克服所述压簧4的弹力推动阀芯2向低压腔17一侧移动至所述肩台22端面压住所述密封垫5时，所述第一连通孔161被封闭。此时高压腔18与低压腔17处于截断状态。因此当所述开关阀70处于关闭状态时，本减压稳流阀40截止进水通道14和出水通道15，隔离进水端高压，保护减压稳流阀40后端的软管和接头。
所述肩台22与所述密封垫5相配合的端面上设有环形凹槽221，所述第一环形凸起162可伸入所述环形凹槽221，第一环形凸起162伸入所述环形凹槽221时，所述环形凹槽221内周面与所述第一环形凸起162的外周面之间留有间隙。
所述环形凹槽221内周面靠近所述第一环形凸起162的一端设有第一倒角2211，第一倒角2211可起到导正作用，这样第一环形凸起162与环形凹槽221做相对运动时，便于第一环形凸起162伸入环形凹槽221内；所述第一环形凸起162内周面靠近所述环形凹槽221一端设有第二倒角1621，第二倒角1621便于水进入第一连通孔161。
阀本体11内侧面与所述隔层16处于高压腔18一侧的连接处间隔设有多个凸筋163，凸筋163的高度小于所述第一环形凸起162的高度。通过多个凸筋163可隔离密封垫5与阀本体11的内侧面，防止安装密封垫5时，密封垫5与隔层16之间形成密闭空间而使得密封垫5无法贴合在隔层16上，影响减压稳流阀40的截止性能。
所述金属垫片31的边缘向外延伸有凸缘311，所述隔层16处于低压腔17一侧设有多个凸块164，处于低压腔17的金属垫片31的凸缘311与所述凸块164相接触时限制压簧4继续驱动膜片3向高压腔18一侧移动，相邻凸块164之间的空间形成过水通道。
所述第二环形凸起131的外周面与阀本体11内壁之间设有密封圈134。
本实施例的工作过程为：当开关阀70处于关闭状态时，冲洗组件80无水流进入，两根冲洗喷头802均不工作。此时相等于减压稳流阀40的出水通道15被封闭，其低压腔17的压力会升高，低压腔17的压力达到设定值时，低压腔17的水压驱动膜片3且经第二 连通孔21传递至所述凹腔19然后克服所述压簧4的弹力推动阀芯2向低压腔17一侧移动至所述肩台22端面压住所述密封垫5时，所述第一连通孔161被封闭。减压稳流阀40处于截止状态。冲洗马桶盖不工作。
当需要进行冲洗工作时，旋转旋钮701使开关阀70的进水口与其中一个出水口连通时，减压稳流阀40的出水通道15先泄压，阀芯2向高压腔18一侧移动打开第一连通孔161，此时减压稳流阀40的进水通道14开始进水，其低压腔17又产生水压，此水压驱动膜片3且经第二连通孔21传递至所述凹腔19然后驱动阀芯2向低压腔17一侧移动，此时阀芯2上的肩台22与所述密封垫5的距离变小，水从高压腔18至低压腔17的过流截面积变小，在这种情况下，水的过流截面积会随进水通道14的压力升高变小，也会随进水通道14的压力降低而变大，因此可以起到出水端减压、稳流的作用，确保减压稳流阀40后面的管路能够减压、稳流；
在这种情况下，加热组件50中的流量传感器就会检测到有流量并把这个信号传输给控制板100，控制板100就接通加热组件50中的电加热管电源开始加热，同时控制板100还能接通电磁换向阀60电源数秒(如5-8秒)后再切断电磁换向阀60电源。管道中的水温较低时，可使得刚接通的水进入自洁管90对冲洗喷头802的喷水口进行清洗，此时加热前较冷的水用于自洁冲洗喷头802，避免冷水冲洗对人造成不适；或因频繁打开开关阀70，加热组件50中电加热管余热使得加热组件50内腔中的水温较高时，刚接通的水也同样进入自洁管90对冲洗喷头802的喷水口进行清洗，避免水温较高烫伤人；
当电磁换向阀60电源被切断后，水温适宜的水就接入冲洗组件80，使得其中一根冲洗喷头802伸出至座圈10中间进行冲洗作业，可旋转旋钮701选择臀洗或妇洗。
本实施例在断电情况下也可进行冲洗。
以上仅是本发明一个较佳的实施例，本领域的技术人员按权利要求作等同的改变都落入本案的保护范围。
